Spurs PG Tony Parker to have MRI on tight hamstring

San Antonio Spurs point guard Tony Parker is scheduled to have an MRI on a tight hamstring on Wednesday, leaving his availability for Game 4 of the NBA Finals very much up in the air.

Parker was injured early in the second half of Game 3 against Miami on Tuesday night. He tried to play through it, but left the game early in the fourth quarter with the Spurs pulling away to an eventual 113-77 victory.
